I will give you 2 points.
y+1=1/3(x-3)
y+1=1/3x-1
y=1/3x-2
If x=0:
y=0-2
y=-2
(0,-2)
If x=3
y=3*1/3-2
y=1-2
y=-1
(3,-1)
Answer=45minutes
three quarters= 3/4 or 75%
an hour is 60 minutes
3/4*60minutes=45minutes
If the x-intercept is 7, then the coordinate is 7 along the x-axis and 0 up the y-axis, so the coordinate is (7,0). We now have the two points (4,2) and (7,0).
You can find out the slope of any line using the general equation:

(0-2)/(7-4) = -2/3
The slope of the line is -2/3x.
